Abstract: PROBLEM TO BE SOLVED: To detect salt water even if the air leaks on the water feed side, by connecting a plurality of decarbonation tanks via a piping, opening an inert gas feed piping at the liquid phase part and a discharge opening at the gas phase pat of each tank. SOLUTION: Each of decarbonation tanks 4-6 has an inert gas feed piping 8 and a discharge opening 9 opened at the liquid phase part and the gas phase part, respectively. A condensate is continuously sampled from a condenser 1 by a pump 2. The sampled water is passed through a cation exchange resin tower 3 to the decarbonation tank 4. A decarbonation inert gas is sent through the feed piping 8 to the liquid phase part of the decarbonation tank 4, where carbonic acid in the solution is removed and discharged along with carbonic dioxide gas through the discharge opening 9. The sampled water out from the decarbonation tank 4 is sent sequentially to the decarbonation tanks 5, 6, thereby, the remaining carbonic acid is completely removed. Thereafter, an electric conductivity of the sampled water is measured by an electric conductivity gauge 7. The sampled water is discharged outside.  Even when air is mixed on the water feed side, the leak of salt water can be detected without being influenced by the carbonic dioxide gas.
